MOTOR VEHICLE.

Application iled March 29, 1928. SerialNo. 265,744.

rlhis invention relates broadly to motor vehicles and more specificallyto 'an improved organization ot trame members for supporting thepropulsion elements thereof.

An obiect of this invention is to construct a vehiclelchassis tramehaving a supplemental remt-'owing structure which is capable ofneutralizing the road's'hocks imposed upon the frame side members andwhich, in addition, is subservient; to the support ot certain drivingand braking adjuncts.

` Another object of this invention is to provide a trame .member whichis so disposed in relation to the driving elements of the vehicle as tolaccommodate the support thereot, and to attord a functional utilitywith certain of the vehicular braking elements.

Another object ot' this invention is to provide a frame structure, theconfiguration ot eert-,ain members of which are congruouswith theappurtenances supported thereby.

Another object of this invention is to provide a frame structure whichis of durable construction, economic design, and which is capable ofbeing erected in bench subassembly.

Other objects and important features of this invention will appear fromthe following description and claims When considered in connection withthe accompanying drawings in which- Y 4 Figure 1 is a plan view of avehicle chassis constructed in accordance with this invention,

' Figure 2 is a transverse section-taken on line 2 2 of Figure 1, and iFigure 3 is a longitudinal sectionv taken on line 3 3 of Figure 2.

Referring to the drawings, the chassis illustrated comprises the usual4front steering Wheels 10, rear or driving Wheels 11, and front and rearaXles 12 and 13 respectively. The axles support the chassis frame 14comprising a pair of side rails 15 connected by a plurality of crossmembers, two of whichv will be presently described. Mounted on theforward portion of the frame '14 is an internal combustion engine 16and'an'opera.- tively associated dynamo 17, and between certain framemembers near the vrear vof the 18 adapted to receive Acurrent from thedynamo 17 and operativelyconnected to the y driving wheels 11. Thesection of the frame'that supports the motors 18 comprises, in additionto the side rails 15, a forwardly disposed transverse rod lf), arearwardly disposed transverse channel member 2t), and a longitudinallyextending channel member 2l connecting the mid points ot said transversemembers. The motors 18 are supported a't vvtheir forward ends bydepending arms 22 clamped to rod 19, and vat their rear ends by hangerarms 23 and 24 secured, respectively, to channel member 2l and siderails 15. As clearly shown in Figures l and 2 ofthe drawing, the casingsot' the motors arcr provided with forwardly eX- tending lugs 25 andtransversely extending arms 2G and 27, which rest respectively upon4supporting elements 22, 23 and 24, above described, and are attachedthereto by bolts 28, 29 and 30.

The chassis comprises manually operated brakes 31 cooperativelyassociated with armature shafts 32 ot. motors 18, and fluid operatedbrakes, not shown, associated With the driving or traction wheels 11.The brakes 31 are mounted on the rear ends of the motors 18, andcomprise brake shoes 33 and 34 engageable with brake drums 35 carried onarmature shafts 32. The shoes 3 3 and 34 are respectivelyattached bymeans of suitable pivotal connections to levers 36 and 37, which leversare ulcrumed on studs 38, screw threaded into the casings of the motors18. The levers 36 and 37 of each brake are connected at their free endsby an actuating mechanism which comprises a ,bell

crank 39 fulcrumed on lever 36, a rod 40 connecting the shorter arm ofthe bell crank with the free vend of the lever 37, and a pair .ofcompression springs 41 encircling the rod 40 and urging the levers 36and 37 apart.

Inasmuch as this mechanism forms no part ot'A the present invention andis of conventional construction, furtherl description is deemedunnecessary. The longer arms of the bell cranks 39 are respectivelyconnected to the opposite ends of an equalizing bar 42 `by means of pullrods 43 pivotally attached 'to both members.

The bar 42, as clearly shown in Figures 2 and 3, is fulcrumed,intermediate its ends, in a shacklel arm 44 articulated to the upper armof a bell crank 45, which crank is pivotally carried by a bolt46-extending between' and throughthe side Walls 47 and 48.01? thechannel member 21. The mounting for the bell crankv 4 5, i1i additiontothe bolt 46, comprises a sleeve -49 surrounding the intermediateportion of the bolt,`and a pair of sleeves mounted upon the first namedsleeve on opposite sides of the crank 45,. securing the same againsttransverse movement. The lower depending arm of the bell crank 45, asillustrated in Figuresl and 3, is connected to a hand operated lever 5lby means of a pull rod linkage comprising a pull rod 52, a relay arm 53mounted at the forward end of channel member 2l, a second pull rod 54, arockerv arm assembly 55, mounted on a cross member 56, and a third pullrod 57.

Thebrakes associated with the wheels are controlled by cams, not shown,mounted on the outer ends of shafts 58. rIhese shafts are operativelyconnected by suitable linkages to diaphragms within the pressurechambers 59 which communicate through conduits 60 and control valve 6lwith a pressure tank, not shown. The control valve 61, as illustrated inFigure 3, is mounted on the channel member 2l slightly to the rear ofthe bell crank 45, and is provided with an operating lever 62operatively connected to a foot pedal 63 by means of a pull linkage.This linkage, as will be readily discerned from the drawings, is similarin arrangement and construction to the linkage which Aconnects the lowerarm of the bell crank 45 to the hand lever 5l. It comprises a pull rod64, a relay arm 65, a second pull rod 66, a rocker arm assembly 67, andthird pull rod hidden within the frame member 15.

Although the foregoing description is necessarily of a detailedcharacter, in order that. the invention may be completely set forth, itis to be understood that the speciic terminology is not intended to berestrictive or confining, and that various rearrangements of parts andmodifications in structural details may be resortedy to withoutdeparting from the scope or spirit of the invention as claimed.

What I claim is:

1. In a motor vehicle chassis, a plurality l,of propeller drive shafts,brakes coopera- "tively associated ywith said shafts, common actuatingmechanism for said brakes, and a longitudinal frame member disposedinter-a mediate said propeller shafts and supporting elements of saidactuating mechanism.

2. In a motor vehicle chassis, a plurality of propeller drive shafts,`brakes cooperatively associated with said shafts, actuating mechanismfor said brakes, and an interior longltudlnal vframe member supportl ingelements of said actuating mechanism.

3. In a motor vehicle chassis, a plurality of propeller drive shafts, aninterior longitudinal frame member affording support for 5. In a motorvehicle chassis, a plurality of propeller drive shafts, a brakecooperatively associated with each of said shafts, a
